To all whom it may concern:

Be it known that I, DMrrRo HRYNIEWIQH, a citizen of the United States ofAmerica, residing at Livermore, in the county of lVestmoreland and Stateof Pennsylvania, have invented certain new and useful Improvements inRailroad-Gates, of which the following is a specification.

This invention relates to certain new and useful improvements inrailroad gates and has for its primary object to provide a railroad gatethat is automatically operated to be moved to either open or closedposition by devices positioned adjacent the track and operable by atrain.

A further object of the invention has reference to a novel form o ftripmechanism adapted for the operation of a railroad gate, the trip devicesbeing arranged in opposed pairs and on different tracks to besimultaneously operated by the passage thereover of trains.

A still further object of the invention resides in the provision of aplurality of trip operating devices for an automatically opening andclosing railroad gate so that a train engaging one of the devices willshift all of said devices and dispose the trip to be subsequentlyoperated by the train in position for engagement by the train.

With the above general objects in view and others that will appear asthe nature of the invention is better understood, the same consists inthe novel form, combination and arrangement of parts hereinafter morefully described, shown in the accompanying drawings and claimed.

In the drawings, wherein like reference characters indicatecorresponding parts throughout the several views,

Briefly described, the present invention aims to provide anautomatically operating railroad gate wherein the gate arms are shiftedfrom their perpendicular to a closing horizontal position, and viceversa by the movement of the train over the track. Assuming that thecross gates are arranged at the outer sides of a pair of tracks, tripdevices are mounted on the tracks in opposed pairs at relatively longdistances at each side of the crossing gate, the opposed trip devices ateach side being mounted on a shaft extending transversely of the twotracks so that the operation of onetrip will effect the operation of thetrip on the other track. The connection between the trip devices and thecrossing gates embodies a plurality of rope sections connectin thetransversely positioned shafts to t e crossing gates while the crossinggates are independently connected by sets of ropes, and in a mannerwhereby the operation of one trip upon a track will set the other tripupon the same track for subsequent engagement by the train to eii'ectthe reverse movement of the crossing gates. 7

It is not intended to limit the invention to the exact details .ofconstruction herein disclosed as the present showin is only believed tobe a preferable embodiment of the invention, the device as hereinillustrated and diagrammatically shown in Fig. 1 embodying applicationto the separate tracks 1 and 2 having a crossing 3, a gate stand 4:being positioned adjacent the outer side of each track 1 and 2 and atopposite sides of the crossing 3 as clearly shown in Figs. 1 and 2 withgate arms 5 pivotally mounted in the upper ends of the stands. At eachside ofthe crossing 3 and positioned a relatively long distancetherefrom is .a transversely journaled shaft -6, the ends of which havea rope connection 7 with the gate stand 4.- while the gate standsareindependently connected by the intermediate ropes 8, trip devices 9being carried by the shaft 6 and each disposed between the rails of theseparate tracks to be operated by a passing train to efiect the openingand closing movement of the gate arms 5 in a man ner to be hereinafterdescribed in detail.

The gate stands 4 and arms 5 are shown more clearly in Figs. 3 to 7,there being provided a casing 10 inclosing a standard 11 having abearing foot 12 at the lower end thereof by which the same is secured tothe casing while the upper end of the standard 11 projects through anopening 13 in the casing and has pivoted 'as at 14 upon the upper endthereof the gate arm 5, the upper.

end of the standard 11 being bifurcated as at 11 as shown in Figs. 4 and5 to accommodate the pivoting block 14 upon the lower end of the arm 5.The standards 11 are provided with sets of brackets and rope pulleys,over which pulleys the ropes 8 connecting the crossing arms at each sideof the track are adapted to pass, and also the ropes 7 extending fromthe shafts 6 to the stands 4,'the standard 11 having a bracket 15 uponthe outer face thereof as shown in Figs. 3 and 4 with three pulleys 16,17 and 18'journaled therein. A bracket 19 projects from the outer faceof the standard 11 adjacent the lower end of the bifurcated arms 11 andhas journaled therein'a pulley 20 and two relatively smaller pulleys 21and 22 respectively, said smaller pulleys being positioned upon theinner end of the bracket arm 19 and within the standard 11 as shown inFig. 3. A stub shaft 23 extends between the side arms 11 of thebifurcated upper end of the standard and has four pulleys 24, 25, 26 and27 journaled thereon, said pulleys 24 to 27 being positioned beneath thegate arm block 14'. The pulley and bracket construction at the oppositeor inner side of the standard is shown more clearly in Fig. 5, thestandard at the lower end thereof supporting a bracket 23 in which apulley 29 is j ournaled while the upper end of the standard at the lowerend'of the bifurcated portion carries a bracket 30 having a pulley 31journaled therein, the pulley 31 alining with the pulley 27 upon theshaft 23.

It is believed that the invention will be better understood with therope connections between the gate arms 5 at each side of the track asfirst described, attention being particularly directed to Figs. 3 to 7,a rope designated by the reference character a is secured at one end asat a to the outer side of the block 14 of one of the arms 5, the ropepassing downwardly beneath the pulley 27, as shown in Figs. 3 and 4 overthe pulley 31 in the bracket 30, downwardly under thepulley 29 in thebracket 28, and thence longitudinally of the track as shown in Figs. 1and 3 for passing beneath the corresponding pulley 29 carried by theopposite standard 11, thence upwardly over the pulley 31, beneath thepulley 27 for attachment to the inner face of the arm head 14 asindicated at a. A second rope connection designated by the referencecharacter 6 has one end attached as at b to the inner side of the block14 of the arm 5, the rope 72 passing clownwardly beneath the pulley 24and over the pulley 20 carried by the bracket arm 19, beneath the pulley18 in the bracket 15., and through the opening 32 adjacent the lower endof the standard for longitudinal travel of the track and passage througha similar opening '32 in the opposed standard 11, thence upwardly frombeneath the pulley 18 for passage over the pulley 2O and beneath thepulley 24 for attachment at its end as at 7) to the outer side of themounting block 14. The rope connections a and 6 between the gate arms 5cause the same to operate simultaneously, the operation of one arm beingcommunicated to the other so that the same will be raised and lowered inunison.

Means is provided for shifting the gate arms 5 and includes thetransversely journaled shafts 6 to which the trip devices 9 are fixed,each shaft 6 carrying a pulley 33 over which the rope 7 passes forcommunicating motion therefrom to the arms 5, the rope 7 being fixed tothe pulley 33 and having the upper strand 0 at the righthand side asshown in Fig. 1 passed beneath the pulley 17 as shown in Figs. 4, 5, and7, upwardly and! over the small pulley 22, beneath the pulley 25 uponthe shaft 23 with the end thereof attached as at c to the outer side ofthe pivot block 14. The lower strand d of the rope 7 passing from theunder side of the pulley 33 passes beneath the pulley 16 in the bracket,15, thence upwardly and over the pulley 21, beneath the pulley 26 withthe end thereof attached as at d to the inner side of the block 14. Theoperating rope 7 for the other arm 5 as shown in Fig. 3 has the upperstrand 0 passed beneath the pulley 17, thence upwardly and over thepulley 22, under the pulley 25 and attached as at c to the outer side ofthe block 14, while the rope strand (Z passes beneath the pulley 16,thenceupwardly and over the pulley 21, beneath the pulley 26 forattachment as at d to the inner side of the block 14'.

The train operated trip mechanism for rotating the shafts 6 to operatethe gate arms 5 is more clearly shown in Figs. 1 and 8 to 10, each tripdevice including a box like casing 34 positioned between the rails ofthe track and through which the shaft 6 is transversely journaled. Atrip lever embodying upper and lower sections 35 and 36, has the lowersection pivoted upon the transverse rod 37 in the casing 34 while alever 38 having one end fixed to the shaft 6 has a link connection 39with the brake joint 40 between the trip lever sections 35 and 36. The

upper section 35 of the trip lever projects through a slotted opening 41in the upper end of the casing 34 and is normally retained in alinementwith the lower section 36 by the coil spring 42 connecting the triplever section 35' to the outer end of the lever 38. A trip device ispositioned on each track and operatively engaged with the shaft 6, andthe normal positions of the trip devices on the same track are thereverse, as shown by full lines in Fig. 8.

From the above detail description of the invention, it is believed thatthe construction and operation thereof will at once be apparent, itbeing noted that a train traveling in the direction indicated by thearrow 43 shown in Fig. 8 has the arm 44 carried there by depending fromthe train in position for engagement with the upper section 35 of thetrip lever. Forward movement of the'trip device 44 will shift the leversections 35 and 36 upon the pivot 37 to rotate the shaft 6 in an obviousmanner, the motion of the shaft 6 being communicated by the rope 7 tothe gate stand 4 and directly to the arms 5 by the connection 0 and d.The rope connections at and b, above described, between the oppositegate arms will effect simultaneous movement thereof while the operationof the distantly positioned trip device 9 is effected through the ropeconnections 7 with the gate arms 5. It will therefore be seen that theoperation of one trip device 9 will effect movement of all of the tripdevices as well as operating the gate arms 5. When the train hasadvanced to place the trip device 44 in the dotted line position shownin Fig. 8 the trip arm section 35 will move on its brake joint 40 withthe section 36 and against the tension of the spring 42 to permit thetrip member 44 to ride over the trip arm section 35, the springrestoring the arm section 35 to its normal position in alinement withthe section 36 in the dotted line position shown in Fig. 8.Simultaneously with this movement, the distantly positioned trip leveron the same track is moved to the dotted line position and disposed forcontact by the trip device 44 on the train. The reverse operation willbe accomplished when the distantly positioned trip lever is engaged bythe trip device 44 to restore the gate arms 5 to their openperpendicular positions. The operation of the several parts is positivein the movement thereof as the parts are connected by rope devices sothat the movement of one part is simultaneously communicated to all ofthe parts. As shown in Figs. 3 to 5, a visual or audible signal may beplaced in the sockets 5 in the gate arms 5 and be suitably timed foroperation with the movement of the gates.

While there is herein shown and described the preferred embodiment ofthe present invention, it is nevertheless to be understood that minorchanges may be made therein without departing from the spirit and scopeof the invention as claimed. v

What is claimed as new is A railroad crossing gate comprising supportingstandards, gate arms pivotally mounted in the u er ends thereof, a pairof rope connections between the lower ends of said arms with theopposite ends of each rope connected respectively to the inner and outersides of the arms, guide pulleys sup ported on said standards over whichthe rope connections pass, train operated means arranged at each side ofthe gate having rope connections with the adjacent gate arms foroperation thereof, the rope connections between the arms .eifectingsimultaneous movement thereof, and guide pulleys supported on saidstandards for the ropes connecting the train operated means to the gatearms.

In testimony whereof I aifix my signature in presence of two witnesses.
